SkyBridge MB-A100/110, published on 10 May 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-23906 in the wild and no public exploit code.\n\nAffected product: Seiko Solutions Inc. SkyBridge MB-A100/110. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-23906/ (Markdown: https://insights.sbomify.com/CVE-2023-23906/index.md)","id":"CVE-2023-23906","markdown":"https://insights.sbomify.com/CVE-2023-23906/index.md","name":"CVE-2023-23906","record":{"aliases":["GHSA-w9q9-jw2h-8gp3"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"SkyBridge MB-A100/110","requires_auth":"none","summary":"Remote unauthenticated attackers can execute critical functions like rebooting the device due to missing authentication in SkyBridge firmware.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jpcert","cpe":[{"product":"skybridge_mb-a100_firmware","vendor":"seiko-sol"},{"product":"skybridge_mb-a110_firmware","vendor":"seiko-sol"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Missing authentication for critical function exists in SkyBridge MB-A100/110 firmware Ver. 4.2.0 and earlier, which may allow a remote unauthenticated attacker to execute some critical functions without authentication, e.g., rebooting the product.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Missing authorization in SkyBridge MB-A100/110","id":"CVE-2023-23906","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2023"},"n_packages":0,"n_references":6,"next":{"headline":"Path traversal in MilesightVPN","id":"CVE-2023-23907"},"packages":[],"prev":{"headline":"This CVE ID has been rejected or withdrawn by its CVE Numbering Authority because it is Unused","id":"CVE-2023-23905"},"products":["SkyBridge MB-A100/110"],"published":"2023-05-10","related":[{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2022-36556","kev_date_added":null,"published":"2022-08-29"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2022-36557","kev_date_added":null,"published":"2022-08-29"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2022-36558","kev_date_added":null,"published":"2022-08-29"},{"cvss_score":6.5,"headline":"Hardcoded credentials in SkyBridge MB-A100/110","id":"CVE-2023-25072","kev_date_added":null,"published":"2023-05-10"},{"cvss_score":4.8,"headline":"Information disclosure in SkyBridge MB-A100/110","id":"CVE-2023-25070","kev_date_added":null,"published":"2023-05-10"},{"cvss_score":4.3,"headline":"Privilege escalation in SkyBridge MB-A100/110","id":"CVE-2023-22361","kev_date_added":null,"published":"2023-05-10"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-01-28","vendors":["Seiko Solutions Inc."]},"summary":"Remote unauthenticated attackers can execute critical functions like rebooting the device due to missing authentication in SkyBridge firmware.","url":"https://insights.sbomify.com/CVE-2023-23906/"}
